Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
I have a parent who he and his son (scout) are invited to a camping weekend listed in the calendar for June. The two of them are shown on the events invitees lists, but the parent cannot see the event when he accesses the calendar. I’ve removed and readded both him and the scout, but that did not solve his issue of unable to see the event.
I am double checking, but I suspect he only has one account, and he can see other events on the calendar. I’ve removed and re-added him to the event, and asked for him to try again. Waiting for his reply.
